Jmod & 1 to 2 shift accumulator torque converter question?

[dcmimpalass]

OK I ordered the parts for the 1 to 2 accumulator and shift piston. I think I will be fine with the tech article on that. But THE TORQUE CONVERTER HAS TO BE DRAINED HOW DO I REFILL IT OR DOES IT REFILL ITS SELF WHEN THE NEW FLUID IS PUT IN?

Ya, the pump will fill it back up. But what's the question on the JMod?

Ok how do I do the jmod withoyt damaging my tranny. cant find the tech article.

The tech article exists so people dont have to explain it! The JMod is rather lengthy explanation but simple project.

You should get new drill bits and use a press, not a hand drill - ideally.

Do a search for "jm

Look in the article for "Jerry's Modification".

I have a 93 mark viii

All I really want to do is change the fluid and correct the 1 to 2 shift. Are I have read that the 95 and later trannys are different, just want to follow the right instructions for the 93. Anybody know?

Do i need to chang the sepearator plate gaskets since I am going to be using merc V?

Ok. The JMod is NOT the change of the accumulators. Often times people confuse them.

The accumulators break and need replacement.

The JMod is designed to extend the life of the trans by reducing fluid pressures. This also quickens and firms up the shifts.

I have not done this in a while, but I dont even think you have to drop the valve body to change them so a new gasket would thus not be needed.

You may want to consider replacing the dipstick tube o-ring. 10 cent part that is very prone to leaking.

1. Drain all fluids and the Torque Convertor also. (there is a plug somewhere on it).
2. Replace the accumulator with the newer/better style.
3. Use a can of trans flush to clear out the trans cooler lines - VERY IMPORTANT!
4. Put pan back on with NEW filter and while the gasket is re-usable, a new Ford OEM one would be recommended due to age.
4. Fill with Mercon V. Maybe 10 quarts at first, then run for a few seconds to fill the TC and repeat with a quart or so till full and shift while running.

Is there a prepunched seperator plate I can just buy to avoid the mistake of drilling the seperator plate incorrectly?

 

[unity]

I think there are sold, but someone else will have to chime in on that. I can not recall who sold them.

Darrin can hook you up with everything from a valve body overhaul kit to a complete blot in valve body assembly.
